[0048] Please refer to Figure 1 - Figure 3 As shown, the vehicle lifting mechanism and scissor lift provided in this embodiment will be described in detail below in conjunction with the accompanying drawings.

[0049] Embodiment 1

[0050] Figure 1 The overall structural diagram of the vehicle lifting mechanism provided in this embodiment is combined with Figure 1 As shown, a vehicle lifting mechanism provided in this embodiment includes: multiple lifting platforms 100, a first connecting rod 200, a second connecting rod 300, a front wheel assembly 400 and a rear wheel assembly 500; at least one first connecting rod 200 and at least one second connecting rod 300 are arranged between any two adjacent lifting platforms 100; the front wheel assembly 400 is detachably connected to the first connecting rod 200, and the rear wheel assembly 500 is detachably connected to the second connecting rod 300, so as to move the vehicle lifting mechanism.

[0051] Specifically, in this embodiment, the vehicle lifting mechanism generally includes two lifting platforms 100, a first connecting rod 200 and a second connecting rod 300. The first connecting rod 200 and the second connecting rod 300 are arranged parallel to the lifting platform 100 and are arranged one in front of the other. It should be noted that at least one first connecting rod 200 and one second connecting rod 300 are arranged between the two lifting platforms 100. In this way, not only the structure is more reliable during lifting, but also the movement is more stable when the front wheel assembly 400 and the rear wheel assembly 500 are arranged.

[0052] Compared with the prior art, the vehicle lifting mechanism provided in this embodiment has the following advantages:

[0053] The vehicle lifting mechanism provided in this embodiment is configured with a front wheel assembly 400 and a rear wheel assembly 500 at the bottom of the first connecting rod 200 and the second connecting rod 300 between any two adjacent lifting platforms 100, respectively, so that the movement of the vehicle lifting mechanism becomes very convenient. In addition, the front wheel assembly 400 and the rear wheel assembly 500 are respectively detachably connected to the first connecting rod 200 and the second connecting rod 300. After the vehicle lifting mechanism is moved to an appropriate position, the front wheel assembly 400 and the rear wheel assembly 500 can be removed respectively. In this way, during the lifting and lowering operation of the vehicle lifting mechanism, the lifting platform 100 is placed on the ground as a whole, and the contact area is large, so that the overall mechanism can maintain a stable state, thereby improving the safety of the operation of the vehicle lifting mechanism and the convenience of use. Finally, in this embodiment, the front wheel assembly 400 and the rear wheel assembly 500 are detachably arranged, so that after the vehicle lifting mechanism is moved to the position where the operation is required, the front wheel assembly 400 and the rear wheel assembly 500 can be removed respectively, which will not affect the use space of the vehicle lifting mechanism during operation.

[0054] Figure 2 Based on Figure 1 The structural diagram of the front wheel assembly 400 of the vehicle lifting mechanism provided in this embodiment, combined with Figure 2 As shown, for the front wheel assembly 400, the front wheel assembly 400 includes a front wheel mounting structure 420 and a front wheel body 410; the front wheel body 410 can be plugged into the first connecting rod 200 through the front wheel mounting structure 420. Further, for the front wheel mounting structure 420, the front wheel mounting structure 420 includes a connecting piece 421 and a first engaging piece 422; one end of the first engaging piece 422 is connected to the second engaging piece 210 on the first connecting rod 200 by engaging, and the other end is connected to the front wheel body 410 through the connecting piece 421. Specifically, a slot is provided at one end of the first engaging piece 422, and the second engaging piece 210 can be engaged in the slot; the top of the connecting piece 421 is inserted into the empty slot at the bottom of the other end of the first engaging piece 422, and the bottom is welded to the wheel axle of the front wheel body 410; the second engaging piece 210 is welded to the first connecting rod 200. In addition, the front wheel assembly 400 further includes a pull rod 430; the pull rod 430 is welded to the axle of the front wheel body 410. The front wheel body 410 mainly includes two front wheel bodies and an axle, and the two front wheel bodies are respectively sleeved on both sides of the axle. The pull rod 430 is welded to the outer side of the axle, which is convenient for the staff to pull the pull rod 430. The connecting rod is vertically welded to the top of the axle.

[0055] In an alternative technical solution of this embodiment, the pull rod 430, the connecting member 421 and the axle of the front wheel main body 410 are integrally formed. The integral formation of the pull rod 430, the connecting member 421 and the axle of the front wheel main body 410 facilitates the overall disassembly of the entire front wheel assembly 400.

[0056] Figure 3 For Figure 1 the structure diagram of the rear wheel assembly 500 of the vehicle lifting mechanism provided in this embodiment based on Figure 3 as shown, for the rear wheel assembly 500, the rear wheel assembly 500 includes a rear wheel main body 510 and a rear wheel mounting structure 520; the rear wheel main body 510 can be inserted and fixed on the second link 300 through the rear wheel mounting structure 520. Further, for the rear wheel mounting structure 520, the rear wheel mounting structure 520 includes a fixing member 521 and two first plug-in members 522; one ends of the two first plug-in members 522 are respectively sleeved on both sides of the axle of the rear wheel main body 510 (for the rear wheel main body 510, it mainly includes a rear wheel body and an axle, and the two rear wheel bodies are sleeved at the central position of the axle), and the other ends are plugged and connected to the second plug-in member 310 on the second link 300; the fixing member 521 simultaneously fixes the first link 200 and the second plug-in member 310 and fixedly connects the two first plug-in members 522.

[0057] For the fixing member 521, this embodiment provides the following two implementation manners to illustrate its specific structure and connection manner:

[0058] Manner 1

[0059] Please continue to refer to Figure 3 as shown, the fixing member 521 is in a C shape, and one end hooks the link, and the other end hooks the second plug-in member 310 and is welded between the two first plug-in members 522. Specifically, the fixing member 521 is in a C shape, the first free end of the C shape hooks the link, the second free end hooks the second plug-in member 310, and the second free end is welded to the two opposite inner surfaces of the two first plug-in members 522. It can be seen that the first plug-in member 522 and the second plug-in member 310 are plugged and connected, so that the rear wheel assembly 500 is connected to the second link 300, and then the rear wheel assembly 500 is fixed to the second link 300 through the fixing member 521, which can prevent the rear wheel assembly 500 from slipping during the movement of the vehicle lifting mechanism and play a reinforcing role.

[0060] Manner 2

[0061] The fixing member 521 is annular and covers the first connecting rod 200 and the second plug-in member 310 at the same time and is welded between the two first plug-in members 522. When in use, the two first plug-in members 522 are welded to the two sides of the fixing member 521, and then the first plug-in members 522 are inserted into the two sides of the axle of the rear wheel body 510, and then the entire rear wheel assembly 500 is slid along the second connecting rod 300 until the two first plug-in members 522 are matched and plugged with the second plug-in member 310 and the fixing member 521 covers the second connecting rod 300 and the second plug-in member 310. When removing, the rear wheel assembly 500 can be completely slid and removed.

[0062] It should be pointed out that the fixing member 521 may also adopt other structures, as long as it can simultaneously fix the first connecting rod 200 and the second connector 310 and fix the two first connectors 522 , which will not be listed here.

[0064] Based on the first embodiment, Figure 1 As shown in FIG. 3 , the scissor lift provided in this embodiment includes the above-mentioned vehicle lifting mechanism, and thus has all the advantages of the above-mentioned vehicle lifting mechanism, which will not be described in detail here.

[0065] It should be pointed out that the scissor lift in this embodiment also includes other structures, but they have all been disclosed as prior art and will not be described in detail here.

[0066] The vehicle lifting mechanism and scissor lift of this embodiment are described above, but this embodiment is not limited to the above specific implementations, and various modifications or changes can be made as long as they do not depart from the scope of the claims. This embodiment includes various modifications and changes within the scope of the claims.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this embodiment, rather than to limit it. Although this embodiment has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
